No, I don't believe it is bridging, I've included the details below... Incidentally, I should be a little more specific and say I am running Roon ROCK, but the principles remain the same.

If you have two ethernet ports, ROCK will display both interfaces in the web config page and allows you to setup the first (labelled 'Ethernet') as your main network and the second (labelled 'Ethernet 2') as the link to the 818's ID41 input. Testing seems to show, if you set these ports up the other way around, Roon won't be able to talk to the ID41.

The fact I am unable to see the ID41 from the main network suggests it isn't bridging, but treating the two as separate networks. So the only ethernet traffic I have on the ID41's network is the music being played, nothing else.

If you want to try this, the recommendation is to setup the second ethernet with:

IP 5.1.1.1
Netmast 255.255.255.0
Router/Gateway: blank
DNS Server: blank

and the ID41 the same, but with an IP address of 5.1.1.2

Hope this helps,
Jeremy

Thanks, I don’t have Rock. I understood a switch was necessary for traffic routing, unless there was “bridging” by the device. Not having such a device, I haven’t had a play.

If it increases SQ, I’m surprised it’s not discussed a little more here (unless I missed something?). I’m aware of the idea being well discussed elsewhere but I’ve not had a play. Interesting. Thanks.

I was very sceptical about it improving sound quality and therefore hadn't tried it before now (and, for all I know, without the other upgrades I've just made, there may not have been any noticeable difference), so I'm not surprised this doesn't come up much (it's also dependant on having two network interfaces, which will further reduce the numbers of people trying this).

There is some support behind this theory, though, as Meridian said noise coming from outside components was something they've worked hard to reduce the influence of and many of the high-end music servers provide two ethernet ports (and some even recommend USB over ethernet) for this reason.

As always, your mileage may vary!

Only just come across ncpl’s good post!

I’ve been using Schucko sockets on my Russ Andrews power cables for years (which I changed to Wattgates and can certainly corroborate your finding that RA cables are built like tanks, and rather difficult to work with and reterminate!)

I also use a dedicated ring main for the aystem. There is certainly a difference and I’m also an advocate that long term impressions are far more useful than short term or quick A/B.

I wondered if you’d tried RA mains filtration? I have various purifiers and silencers, etc., which again made things sound better. RA also have a device called the ‘noise sniffer’ which you can hire for a small fee to hear crud on the mains (and the difference in removing it).

Are you tempted by ‘balanced mains’ units...?

Sorry, I've only just seen your post.

I certainly believe RA cables make a difference, however I wanted to take my audio path to the next logical conclusion and my particular path took me to the Shunyata Triton (rather than RA's mains filters). Having seen the difference the GISO ethernet isolator makes (likely to be retired for an Sotm ethernet filter), I would like to try balanced mains cabling but fear it may clash with what the Triton is trying to do.

I think my next step is to upgrade the Triton v2 to the Triton v3...

Definitely upgrade your Triton v2 to the v3 -- you'll be very pleased by the improvement. There was a review of the v3 on www.audiostream.com a few months ago that I think accurately describes the differences.

On the balanced mains issue, I played around with Equitech balanced line conditioners years ago, but they always sounded thin to me. A friend sprung for one of their very expensive (and massive) wall units and swore by it for a long time, but then someone lent him an Audioquest Niagara 7000, and he was amazed at how much cleaner and more natural everything sounded (he wound up buying one).

I can't say for sure why that would be the case, but I do know both the Audioquest and Shunyata units are designed to isolate individual components from other each other, whereas the Equitech is basically designed to isolate the entire system from the outside world.

@Cleop Thanks for the additional info.

My background research seemed to show that balanced mains would improve the grounding by delivering a stable ground, unaffected by appliances that have ground as a sink for EMI noise, whereas the Shunyata Triton actually removes a great deal of noise from all lines (live, neutral and ground). This approach, along with the reviews, convinced me that this was the route to follow.

I agree the upgrade to the v3 is the way forward. My understanding is that the Triton v2 reduces mains noise by around 24dB whereas the v3 is closer to the Denali which reduces noise by an astonishing 60dB. I'm just waiting to find out whether Shunyata is now accepting upgrades from units outside the US...

Have you tried the Sotm filter? In the end I went for an Acoustic Revive Gigabit version. But Sotm are interesting and pushing forward.
